After brushing the waterproof, what should I do if the putty is batched, and the wall is still alkal

Your wall is so alkali return, indicating that the exterior wall has cracks, holes and other defects, these reasons are caused by the construction of the building, how you do it indoors is useless, you must deal with the exterior wall, and then spray 10% concentration of aluminum nitrate aqueous solution at the indoor alkali return, remove the alkali return after drying, and then carry out construction such as scraping Dabai, so as to ensure that there is no problem.

You suspect that the workers have fooled you and wronged others!

It must be noted that in the absence of any technical solution, you blindly construct, and the putty is constructed on the waterproof layer, can it be firm? I'm deeply disturbed, I don't know what kind of waterproof material you use, I think that before the putty is approved, the base layer must be handled to ensure that it is compatible with the putty material. It is best to call a technical solution provided by the construction party and have relevant commitments.

Your question is obviously a leak in the exterior wall. Plug the leak first, and then carry out the internal putty construction when there is no problem. Backwater waterproofing is difficult to do on indoor walls.

Waterproofing like this is generally cement-based.。 Also, if you are talking about the anti-alkali part is against the ground, or the window, the bathroom. You can consider external factors now.

facades. The ground is damp. The walls of the bathroom are permeable.

Problems like this can occur ...

First of all, there was a problem with the waterproofing. What material is used. It's cheap. Treated with CF-200 high-efficiency composite waterproofing agent (cement-based permeable crystalline type), it will definitely not be alkali-resistant.

You can do some wall paint.

Summary. Pro, the wall alkali re-brushing putty has water beads abnormal, the treatment method is: 1. Brush the alkali wall several times with a hard brush (it must be dry brushed, washed or neutralized with acid is impossible to remove completely), and then clean.

Second, the first putty bottom adopts the construction process of exterior wall waterproof coating, that is, the construction white cement putty powder is mixed with JS waterproofing agent and then the base is laid. Third, the subsequent procedures can be carried out according to the normal coating construction process. The wall alkali is formed by the silicate and carbonate in the wall material when it encounters water or moisture and crystallize, so far it is still not completely **, it is recommended to keep the room ventilated and dry after decoration, so as to effectively avoid the wall back to alkali again.

The wall alkali is the silicate and carbonate in the wall material when it encounters water or moisture and crystallizes to form cherry blossom change, so far it is still not completely **, it is recommended to keep the room ventilated and dry after decoration, so as to effectively avoid the wall back to alkali again.

The cracks between the floor tiles and the walls are wet.

You can open the window and air dry.

Could it be that the mud under the floor tiles is damp and the wall is alkalinized.

Yes.

1. If there is putty and anti-alkali on the wall, you can use a brush and waterproof paint to paint the wall, first wash the anti-alkali place on the wall, you can wash it several times with a brush, and then apply anti-alkali cleaner on the brush, and pay attention to the uniform distribution when applying, and finally apply the professional waterproof paint on it. 2. If there is no brush and waterproof coating, use a shovel and polyurethane paint, first get the anti-alkali wall skin down with a shovel and wash it, and then combine the white vinegar and water ginseng in equal proportions, it is recommended to find a professional maintenance master.

1. Because the alkali content of the material is too high, you can choose to use professional tools and coatings to wash the wall, generally use brushes and waterproof coatings, and then carry out the corresponding operations, you can no longer make the wall putty have the phenomenon of anti-alkali.

2. It may be improperly handled when decorating, you can choose to use a shovel and polyurethane paint, but you must pay attention to the proportion when using, so as to ensure that the wall is treated cleanly.

Excuse me, but please go into more detail?

In response to this problem, generally speaking, after the wall is soaked in water and alkali, it is necessary to wait for the wall to be completely dry before brushing putty. In general, you need to wait 2-3 days for indoor walls and 3-5 days for outdoor walls, depending on the sail and the local temperature and humidity. Before brushing putty, it is also necessary to treat the wall, such as cleaning the wall, removing dirt, smoothing out the uneven places on the wall, and hollowing the wall.

These treatments take a certain amount of time, so it generally takes 5-7 days from the wall soaking in water to the final putty. In addition, before brushing the putty, the wall also needs to be waterproofed to prevent the putty layer from being penetrated by water, which will affect the quality of the putty layer. Generally speaking, you can use latex paint or gypsum powder to waterproof the wall to ensure the quality of the greasy stare layer.

In short, it generally takes 5-7 days from the wall soaking in water to the final putty, including wall drying, cleaning, leveling, waterproofing and other treatments.

How to deal with the alkali on the wall of the second-hand house thoroughly, for this problem, whether it is a new house or a second-hand house, as long as it is a long time, there will be more or less alkali on the wall, at this time, when you see the putty layer on the wall peeling off, not only affects the mood of the whole day, but also will be troubled by the living environment.

First, first of all, how to thoroughly dispose of the alkali on the wall.

1.How to thoroughly treat the alkali on the wall, if it is permeable, is mainly due to the high water absorption of the outer wall material.

1) Some water-soluble chemicals will be immersed into the stone through the capillary tubes in the stone, with water as a carrier. How to deal with the alkali return of the wall before scraping puttyThe pores of the surface material are channels, water, alkalis, salts and other substances that penetrate and precipitate in the binder material. After the water evaporates, the white crystals of salt water and alkali will remain on the surface of the stone and become alkaline.

2) Solution: When processing, it is necessary to purchase surface materials with higher density and cement materials with lower alkalinity, and then adopt dry suspension construction technology to avoid wet bonding. Finally, a waterproofing treatment is applied, and a waterproofing material is applied to the cement or cement-gypsum layer, followed by an adhesive.

2.If only the surface is returned to alkali, it is mainly due to the low density of the material and the difficulty in absorbing water.

1) When the material contains chemically unstable alkaline impurities, salts are formed, such as carbonates, and white crystals appear on the surface after the water evaporates.

2) Solution: If this is the case, the treatment method is mainly to clean the surfaceHow to deal with the alkali return of the wall before scraping puttyIt is possible to combine surface contamination and acid rain reaction of the material during use, and use a percentage of the solution oxalic acid for regular cleaning.

Second, how to maintain the interior walls.

1. Clean special spots.

If it is a stain that is difficult to remove, use fine sandpaper to gently wipe the stain and then repair it with wall paint, and the wall will stay clean.

2. General cleaning point.

Interior walls are usually covered. If there are stains on the wall, they should be removed in time. How to deal with the alkali return of the wall before scraping puttyIf they are waterproof, wipe them with a cloth and dry them with a dry towel.

If it is not waterproof, you can only use an elastic band to clean the walls.

3. There are cracks in the wall.

Cracked walls can also be cracked, cracks can be scooped up directly and then repaired, sanded and leveled with the same paint color to enhance the aesthetics.

4. For mildew.

How to deal with the alkali return of the wall before scraping puttyMould conditions are often found on interior walls, especially in bathrooms and kitchensHow to deal with the alkali return of the wall before scraping puttyThese walls are prone to mold and affect the appearance of the walls. In the case of molds, you can clean with chlorine, not only to remove mold from the surface, but also to disinfect.

The above is all the content, for the second-hand house wall alkali how to thoroughly deal with the problem of how to maintain the indoor wall, I believe that after you read it, now you are basically clear about it! Moreover, alkali on the wall is a frequent problem, if this happens to the wall of your home, it is recommended to deal with it thoroughly as soon as possible to avoid a greater impact on the living environment.

The problem of anti-alkali in the wall is usually caused by improper treatment of the base layer or the use of unsuitable materials. Oxalic acid is a chemical agent that removes the alkalinity of the wall, if there is an anti-alkali situation after brushing oxalic acid, it may be caused by the putty material is not suitable or the construction is not in place.

In this case, it is advisable to find the cause of the anti-alkali first, rule out the problem of the base layer, and then use suitable materials and processes for repair and coating. Specifically, the following measures can be taken:

Carry out base treatment on the wall, clean up the old putty and loose surface, and deal with the base layer problem.

Use suitable putty materials, apply according to requirements, and fully dry and cure.

Apply primer to seal the base layer and strengthen the adhesion and alkali resistance of the wall.

Use the appropriate coating for coating, pay attention to the thickness of the coating and the drying time to ensure that the coating is firm.

After the painting is completed, the wall surface is fully ventilated and dried to ensure that the coating is dry and cured.

It should be noted that in order to avoid the recurrence of the situation of anti-macro alkali change, the construction should be carried out in strict accordance with the requirements of the use of materials and process requirements to ensure that the base treatment and material selection of the wall are correct.
